LYV® Hand gate valve Introduction

You can rest assured to buy customized Manual Gate Valve from LYV®. We look forward to cooperating with you, if you want to know more, you can consult us now, we will reply to you in time! Manual gate valve is a control component that moves through the hand wheel drive gate along the channel axis in the vertical direction to cut off the medium flow in the pipeline system. In the process of use, the valve must be fully open or fully closed, and cannot be used to regulate the flow.

When the gate valve is closed, the sealing surface can only rely on the medium pressure to seal, that is, only rely on the medium pressure to press the sealing surface of the gate to the seat on the other side to seal the sealing surface, which is self-sealing. Most gate valves are forced to seal, that is, when the valve is closed, to rely on external force to force the gate to the seat, sealing surface tightness.

The Manual Gate Valve whose gate plate moves in a straight line with the stem is called lifting rod gate valve (also called open rod gate valve). Usually there is a ladder thread on the lifting rod, through the nut at the top of the valve and the guide groove on the valve body, the rotating motion into a straight motion, that is, the operating torque into the operating thrust. Some valves, the stem nut is located on the gate, the hand wheel rotates to drive the stem to rotate, and the gate is lifted. This kind of valve is called rotating rod gate valve or dark rod gate valve.
